Hi Peter,
I recommend using the following handy little idiom:
\ctxlua{commands.doifelse(-45 0)}{big}{small} % small
It lets you do all sorts of things that are tricky in TeX:
\ctxlua{ commands.doifelse( string.len( -45 ) 5 ) }{long}{short}

For functions in the commands namespace you can write e.g.
\ctxcommand{doifelse(…)}{…}{…} instead of \ctxlua{commands.doifelse(…)}{…}{…}.

Re: [NTG-context] test for (negative) number
Thanks for all the answers so far. The 'doifelse' should do the trick. I
was hoping for a system macro, but if there is none, I have to program
it myself. :-)

Re: [NTG-context] test for (negative) number
... I also found another solution reposter before:
\ctxlua{commands.testcase(condition)}
{ If true...}
{If false}
Note that both blocks (if-true and if-false) are mandatory.
Considering Wolfgang's last answer, it would be better to write:
\ctxcommand{testcase(condition)}
{ If true...}
{If false}

yes, but testcase is an unfortunate name and sort of obsolete (so best
use doifelse)

[NTG-context] test for (negative) number
Hi,
I used '\doifnumberelse' to validate some macro parameters (angle).
Sadly it does not work with negative numbers. Is there a similar macro,
that also supports negative values?
Example:
\doifnumberelse {45}{yes}{no}% yes
\doifnumberelse{-45}{yes}{no}% no
Greetings, Peter
